WOOL-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 784,240, dated March *7, 1905.

Application filed April 29, 1904. Serial No. 205,578.

To (Z/ZZ wit/1711 it may concern:

Be it known that I, JOSEPH H. TILLINGHAS'I,

' a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Tool-Washing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in-the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to certain improvements in that class of forking, elevating, and conveying machines used for handling fibrous and analogous materials during the cleansing process, more particularly wool.

My object is to introduce a more cheaplyconstructed machine which will thoroughly agitate the wool while in the washing tub or vat, convey the same to the end of said tub or vat, and then elevate said wool to a conveyer, which deposits it into the squeeze or Wringer rolls regularly by mechanical means automatically, my principal object being to reduce the wearing parts to a minimum, so as to require less power to operate and prolong the life of the machine. This I accomplish by the peculiar construction, novel combination, and adaptation of parts hereinafter described, and particularly pointed out in the claims hereunto annexed, reference being had to the accompanying drawings for a better understanding thereof, in which- Figure 1 is a side elevation of my improved machine. Fig. 2 is a front elevation of the same, showing the swing-frame, power-shaft, fork, and posts. Fig. 3 is a detached side elevation of the fork-operating mechanism viewed from the fork 10", and Fig. 4C is an elevation of the same viewed from the opposite side or outside of the tub or vat. Fig. 5 is a plan view of my machine, showing more particularly the construction of the rake and its supporting mechanism.

Similar figures of reference indicate corrcspending parts throughout all the views.

1 represents the squeeze or wringer rolls, which are of the form and function of those in general use and are located in suitable bearings at one end of a suitable tub or vat 2, such as is used for washing wool or other analogous fibrous material. An apron or conveyor formed, preferably, of series of rollers 3 is located in juxtaposition to the squeeze-rolls I over the tub or vat 2, as shown in Fig. I.

I arrange and attach posts 4: one on either side of and at a suitable point longitudinally on the vat or tub '2 and directly opposite to each other. A power-shaft5 is journaled on the said posts I near the top of the same in suitable bearings. Said power-shaft 5 is operated by a power-pulley 6, rigidly attached thereto. A swing-frame is suspended from and pivoted to the shaft 5 and is composed of the oscillating arms 7, which have their upper ends journaled on the shaft 5 and the crossbar 8, adapted to stiffen the said arms '7. The arms 7 at their lower ends are adapted to carry a fork-shaft 9, which is journaled thereon.

Said fork-shaft 9 is provided with a fork 10,

rigidly secured at a suitable point thereon. The fork 10 is operated intermittently by means of sprocket wheels and chains extending between said shaft 5 and said shaft 9. I use preferably three of the arms 7, two of which are arranged close together, as shown in Fig. 2, between which the shaft 5 is adapted to carry a sprocket 11,1-igidly secured thereto. A sprocket-chain 12 engages the wheel 11 and communicates motion to a similar sprocket-wheel 13, which is loosely mounted or journaled on the shaft 9 between the arms or members 7 The sprocket-wheel 11 is adapted to make six revolutions to two revolutions of the sprocket-wheel 13, while the said shaft 9 is making one complete movement forward and back, as more fully hereinafterdescribed. A cog-wheel 14: is also journaled on the shaft 9 and attached to and adapted to revolve with the said.

sprocket-wheel 13. A similar cog-wheel 15,

adapted to engage said wheel I i through the medium of an idler 16 hasa shaft 17 and is suitably journaled in brackets 18 on the oscillating arms 7, as shown in Figs. 1 and 2. The inner end of said shaft 17 is adapted to carry a double cam 19, which is adjustable by means of a slot 20 and cap-screw secured in the end of the shaft 17. The earn 19 is provided with two pins 21 and 22, one longer than the other, for the purposes as will be shown herein. The saidwheel 15 is adapted to make one revolution to two revolutions of the wheel 14. The shaft 9 between the oscillating arms 7 is adapted to carry a fork-operating ratchetwhccl 23, which is rigidly attached to the same. The wheel 23 has a slot in its periphery in which is fitted a removable lug 24, which is rigidly secured to the side of said wheel 23', and has a slot25, (shown more particularly in Fig. 3,) which is adapted to be engaged intermittently by a pawl 26, which is carried by the sprocket-wheel 13, which has a lug 27 in its side for that purpose. pressed into engagement with the slot 25 by a spring 28, which has one end rigidly attached to the side of the wheel 13, the other end engaging with said pawl 26. Said pawl 26 has a lug on one end which is adapted to engage with the pin 21 at each alternate revolution of the wheel 13, said pin 21 and cam 19 being adjusted so to do. The lug 24 protrudes from the side of the wheel 23 and is adapted to be engaged by a pawl 29, which is pivoted to one of the arms 7, as shown in Fig. 2. The lug 24 has an auxiliary notch 30 to the rearward of the slot 25 for the purpose as will be shown.

A rake-frame composed of the longitudinal bars 31 and the cross-pieces 32 is suspended from and operated by cranks attached to shafts and journaled above the tub 2 and rake aforesaid. There are four cranks 33, two forward and two to the rear, which have connecting-rods 34 attached to and supporting the said rake-frame. The shafts 35 are journaled on a frame 35, erected over the tub for that purpose. The shafts 35 are driven by means ofa sprocket-chain 36 from a sprocket 37 on the power-shaft 5 to a sprocket 38 on the forward shaft 35. The rear shaft 35 is operated simultaneously with the forward shaft 35 by asprocket-chain 39,connecting two similar sprockets 40 on the said shafts 35. The swing-frame 7 8 with its fork 10 is oscillated by means of pitman-rods 41, which have one end pivotally attached at a suitable point on the arms 7 and the other ends pivoted to the forward cranks 33.

The rake-frame 31 32 is oscillated to and fro by pitman-rods 42, attached thereto and to ,the shaft 9. The rake-frame has rakeshafts 43 arranged with their length crosswise on said frame, which are journaled in suitable bearings and provided with tines or teeth 44 depending therefrom. Said shafts 43 have upwardly-extending arms 45, which The pawl 26 is.

are connected together by a rod or bar 46, as shown in Fig. l. A pitman-rod 47 has one end attached to the top end of the forward arm 45 and its free end adjustably attached to one of the arms 7 for the purpose of oscillating the rakes 44.

Each part having been properly adjusted, power is applied to the pulley'6 and shaft 5. The relative sizes of the sprockets 13, 11, 37, and 38 are such that the shaft 35 will make one revolution as the wheel 13 is making two. The cranks 33 are adapted to oscillate the frame 7 8 through the medium of the pitmanrods 41, at the same time raising and lowering the rake. As the shaft 9 and fork 10 recede from the squeeze-rolls 1 and feed-rolls 3 the ratchet-pawl 26 engages the slot 25, thus revolving the shaft 9' and fork 10 through the medium of the ratchet-wheel 23. The above mechanism is revolved rearwardly so as to turn the fork over the shaft 9 as the same recedes, said fork 10 being about to descend into the tub as the shaft 9 reaches its rearward limit. As the forklO and shaft 9 begin their forward movement, said fork dips into the tub or vat, gathering its fibrous contents upon its members whereupon as it reaches a horizontal position the pawl 26 reaches a point in its revolution where its end engages with the pin 21, which is adjusted so as to be at a point in its revolution nearest the shaft 9. As the said pin 21 engages the pawl 26 it is disengaged from the slot 25 and the rotation of the fork ceases and is held from dropping back by the pawl 29, which engages the slot 25. Atthe same time the forward movement of the fork and its load continues until carried over the rolls 3, when the pin 22 reaches a point in its revolution, having been adjusted so to do, where it engages the said pawl 29, releasing the same from the notch or slot 25, allowing the fork 10 to drop on the said rolls 3, which draw the material fromthe fork. The fork then begins to recede again and is held imposition by the pawl 29, which engages the notch 30, after the pin 22 disengages said pawl, until the pawl completes its second revolution and engages the slot 25. The pins 21 and 22 are adapted to be at their greatest distance away from the shaft 25 as their respective pawls are carrying the fork, so as to allow it to pass without tripping. As the frame 7 8 and shaft 9 recede from the rolls 3 and 1 the cranks 33 are rotating over the shafts 35 and at the same time raising the rake 31 32. As the cranks pass rearwardly the rake is also carried rearwardly by the pitman 42. The rake is dropped into the tub 2 by the cranks 33 and are drawn forward by the forward motion of the shaft 9. The rakes 44 are given an oscillating motion by the rods 46 and 47, which are controlled by the arm 7.

h Iany features shown in my drawings are not new; but I have shown them only to illustrate the connection of my invention therewith. Such parts I do not claim, broadly; but
